A voice teacher from Haverhill is being charged with impregnating his teenage student.

The 14-year-old girl denied any sort of sexual relationship with her 32-year-old teacher, Joshua Garsteck, claiming she got pregnant through a relationship with a man she met online. But when authorities searched her phone records, they found a trove of text messages between the girl and her teacher, the Eagle Tribune reports.

"There are thousands of text messages between this defendant and this child,” Assistant District Attorney Jessica Strasnick told the EG. “There are text messages between this defendant and the child’s mother, and there are text messages between this defendant and what appears to be another juvenile, who is in the process of being identified.”

She added that the messages between Garsteck and the victim were “graphic and sexual.”

“I know we’re familiar with the term ‘sexting,’ but I suggest that ‘sexting’ is a gross understatement for the content of the defendant’s text messages,” she said. “They truly shock the conscience that an adult would text such graphic details to a child.”
